XQB小型泥漿泵的結(jié)構(gòu)設(shè)計(jì)畢業(yè)論文.doc

1摘要灌用泥漿泵被廣泛的應(yīng)用在水庫(kù)大壩、煤礦巷道、隧道灌漿、高速公路邊坡維護(hù)、建筑地基加固等場(chǎng)合，隨著國(guó)民經(jīng)濟(jì)的發(fā)展，此類(lèi)泥漿泵的需求量也越來(lái)越大。近年來(lái)，灌用泥漿泵的研制和發(fā)展也越來(lái)越快，但其也存在著許多的問(wèn)題：一是此類(lèi)泥漿泵的平均無(wú)故障的工作時(shí)間較短，最多也就幾個(gè)小時(shí)；二是重量和體積普遍較大，野外搬運(yùn)不便；三是更換密封件的時(shí)間較長(zhǎng)。針對(duì)以上問(wèn)題的提出，本次設(shè)計(jì)有了具體的解決措施，解決密封件壽命短的問(wèn)題，關(guān)鍵是選擇合適的密封材料和合理的結(jié)構(gòu)形式；為了使泵的整體重量減輕，就要徹底放棄傳統(tǒng)的減速方式，取而代之的是先進(jìn)的減速方式，本此設(shè)計(jì)選用的是行星減速器大傳動(dòng)比降速，并將行星減速器置于大帶輪中，既能夠達(dá)到降速的目的，又能夠減輕泵的總體重量。關(guān)鍵字：密封件行星減速器壓力流量柱塞2AbstractFedsludgepumpiswidelyusedintheapplicationofdamreservoirs,coalmine,tunnelsfilled,lengthofthehighway,constructionoffoundationreinforced,andsoon,withthedevelopmentofthenationaleconomy,thedemandofsuchsludgepumpisalsogrowing.Inrecentyears,fedbysludgepumpresearchanddevelopmentisgrowingfast,buttherearestilltheexistenceofmanyproblems:First,theaverageno-faultsludgepumpshorterworkinghours,uptoseveralhours；Second,theweightandsizegenerallylargerfieldhandlinginconvenience；Thirdisthereplacementofsealedpiecesoveralongerperiodoftime.Respondingtotheabovequestions,thisdesignhasspecificsolutionstoaddresstheshortlifeofthesealed,thekeyistochoosesuitablematerialsandsealedreasonablestructure；Inordertomaketheoverallweightpump,wemustcompletelyabandonthetraditionalslowdown,replacedbyadvancedslowdown,Thedesignchosenisthelargetransmissionplanetaryreducerthanpaved,andundergreatDailunplanetaryreducer,bothcanbeachievedfasterpurposes,andtoreducetheoverallweightpump.Key:sealedpiecesplanetaryreducerpressureflowpiston3目錄摘要.1Abstract.2目錄.3前言.5第一章泵的總體設(shè)計(jì).7第二章原動(dòng)機(jī)的選擇.9第三章吸漿管與排漿管的選擇與直徑計(jì)算.12第四章泥漿泵零件選擇及其強(qiáng)度的計(jì)算.134.1機(jī)架.134.2泵體.134.3連桿十字頭連接處銷(xiāo)子強(qiáng)度的計(jì)算.134.4柱塞上螺紋強(qiáng)度計(jì)算.154.4.1螺紋的選擇和強(qiáng)度校核.154.4.2螺紋連接的防松方式的選擇.174.5泵體壁厚強(qiáng)度計(jì)算和選擇.174.6空氣室容積及強(qiáng)度計(jì)算和選擇.184.7減速器的選擇和計(jì)算.204.8V帶傳動(dòng)的計(jì)算.234.9軸的設(shè)計(jì)和強(qiáng)度校核.264.9.1估算軸徑d.264.9.2軸的受力分析.264.9.3驗(yàn)算軸徑.304.10軸承選擇.314.10.1軸承壽命計(jì)算.324.10.2靜載荷計(jì)算.324.11軸上鍵的選擇.334.11.1平鍵的選擇.334.11.2平鍵的強(qiáng)度校核.334.11.3花鍵的選擇.334.11.4花鍵的強(qiáng)度校核.3344.12活塞密封圈的選擇.344.13.泵的潤(rùn)滑.34第五章泵的使用和維護(hù).365.1用途.365.2結(jié)構(gòu).365.3安裝.365.4維護(hù)與保養(yǎng).36第六章X
